APPARATUS FOR TRANSPORTING LOGS.

Specification of Letters Patent.

Patented July 1, 1913.

Application filed April 12, 1912. Serial No. 690,457.

To all whom it may concern Be it known that I, FREDERICK W. Vinn- ING,citizen of the United States, residing at Davis, in the county of Tuckerand State of West Virginia, have invented certain new and usefulImprovements in Apparatus for Transporting Logs; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to improvements in means for transporting logs.

In my prior Patent, No. 1,015,103, dated January 16, 1912, I illustratedand described a mast provided with a cap constructed in such manner asto necessitate the main cable being passed over a guide pulley attachedto a support located to one side of the apparatus. My present inventionis primarily designed to avoid this contingency, and the improvement isdirected to the features which will permit of the main cable passingdirect from the housing at the top of the mast to the guide pulleys inthe lower portion of the mast and thence to the operating drum. v

My invention also comprehends improvements in the means employed forbracing the mast in opposition to load strain when hauling logs.

The invention also relates to the specific details of construction andarrangement of parts which will be hereinafter described andparticularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation illustrating theapplication of my invention. Fig. 2 is an enlarged elevation of themast, parts being shown in section. Fig. 3 is a detail plan view of themast cap. Fig. 4 is an end elevation of the same. Fig. 5 is adiagrammatic perspective view of the arrangement of the blocks and thebracing cable adjacent the top of the mast.

1 indicates a car, supported on wheels 2, and adapted to travelon thetrack 3. On the car is a base 4, comprising a lower stationary section5, preferably supported on sills, and a rotatable upper section 6,having hinged at 7 amastsocket 8, locked in position by a latch 9.

Fitted in the mast socket is a mast 10, formed at its lower end with avertical opening 11, the upper portion of which merges into an open slot12. guide rollers 14:, over which a main or cable track 25 passes, andbelow the opening, and suitably supported below the lower station arysection 5 is a guide roller 15.

On the upper end of the mast 10, is secured a cap 16, formed with aflange 17 on which are bolted two parallel vertically disposed spacedplates 18, between which a series of rollers 19 are mounted. To theupper ends of the plates 18, is bolted a tip 21, having a trunnion 21which receives a support 21 for the upper ends of guys 22. The lowerends of the guys 22 are staked or otherwise anchored to hold themaststeady when the apparatus is set up for op eration. Each roller 19,is mounted in a different vertical and horizontal plane than theadjacent roller to form a gradual curved track for the main cable, theperiphery of the lowest of said rollers being slightly beyond the planeof the outer surface of the mast, as clearly shown in Fig. 2.

The inner end of the main or cable track 25, is wound on a drum 26, fromwhence itpasses over the guide pulley 15, and thence through thevertical opening 11, and over the guide pulleys l4, and up along theouter surface of the mast to the rollers 19. From the rollers 19, themain cable extends above the plane of the forest being worked, and issecured to a stump or tree as indicated at 30.

Mounted to travel on the main or cable track 25, is a carriage 31, whichis operated from the car, in substantially the same manner, shown anddescribed in the beforementioned patent.

In the slot 12, are two The cap 16 is provided with a lateral eye 33,which supports a block 3 1, including two pulleys 34 and 34-." aroundwhich the cable 35 passes. The cable 35 comes from a drum 36, and isguided under a pulley 37 on the.

mast, and thence around a pulley 35 swiveled to the mast below the block34:. From pulley 35*, the cable 35 passes around pulley 34, thencearound pulley 38 mounted in a block 33, thence around pulley 34:", inblock 34, and its free end is fastened to an eye 38 on block 38. Block38, is secured to guy cables 41, the ends of which are anchored tosupports or stumps of trees as indicated at 42.

In operation, the carriage 31, is drawn out on the cable track byoperating the drums, and the hoisting cable is lowered and the logs aresecured. hen the logs are elevated great strain is placed on the cabletrack, which has a tendency to pull the top of the mast in direction ofthe load. As the logs are drawn up toward the carriage, the drum 26 isrotated to take up as much slack as possible on the, cable track, whichmaterially increases the pull on the upper end of the mast. To overcomethis tremendous pull at the top of the mast, it is of the utmostimportance that powerful means be provided to counter-act the tendencyto draw the mast down. Hence, it is essential that the bracing cable beunder such perfect control to regulate its tension to accommodatedifierent loads when hauling toward the mast. Now, when a load israised, the drum 36 is rotated, and because of the arrangement of thebracing cable, and its connections between the upper end of the mast andthe guys 41, the mast is braced in opposition to the load strain exertedby the load on the cable track. Therefore the pull on the mast by thebracing cable can be regulated according to the load pull on theopposite side of the mast, during any period of the operation of haulinglogs, which is ,of considerable importance, in that it insures stabilityof the parts, and permits of a ready means for releasing the strain onthe cables when the apparatus is not in use.

The cable 35, performs a dual function. It acts as a brace to resist thestrain, due to the weight of the logs being hauled, and it acts as ameans for moving the car on the track to change the position of theapparatus. If it be desired to move the car, the carriage operatingcables, and the main cable are slackened, and the operating drum 36 isrotated to wind the cable 35. The winding of the cable 35, will advancethe car on the track to the desired position, and then by tightening thepreviously released cables, the cable 35 again becomes a brace for themast.

I have found by practical experience the construction and arrangement ofparts described enables me to perform the operation of hauling logs witha great deal of expedition, and with greater degree of surety of bracingand steadying the parts. I am also enabled to quickly shift the guycables 22, and the main cable 25, and turn the mast and operate over anarea disposed at various angles from the car. By placing cable 25, asshown and described, I am enabled to change the position of the cablewith considerably less trouble and expense, and can at the same timeremove logs from a much larger area than is possible with apparatusesnow in use.
